| 摘 要： | 研究了宁南旱区坡耕地不同条带种植对谷子的产量、水分利用效率及旗叶光合特性的影响.结果表明:带状休闲轮种能增加谷子产量,提高其水分利用效率.条带种植处理Ⅰ、Ⅱ产量分别高出对照50.74、123.33 kg/hm2,差异极显著,水分生产效率分别比对照高0.1、0.79 kg·hm-2·mm-1;条带休闲轮种可显著提高谷子叶片光合速率(Pn)和瞬时水分利用效率(WUEP),灌浆期条带种植处理Ⅰ、Ⅱ的Pn分别高出对照1.320、1.794 μmol·m-2·s-1,WUEP比对照分别高1.31、1.03 μmol·mmol-1.休闲轮种有利于增强谷子干物质积累能力,提高其群体水分利用效率.干物质积累量处理Ⅰ、Ⅱ拔节期显著高于对照,抽穗期、灌浆期和成熟期极显著高于对照.条带种植处理Ⅰ、Ⅱ主要生育期谷子群体水分利用效率(WUED)均显著高于对照.
